Fringe benefits aircraft valuation formula. The Standard Industry Fare Level (SIFL) cents-per-mile rates and terminal charges in effect for the first half of 2005 are set forth for purposes of determining the value of noncommercial flights on employer-provided aircraft under section 1.61-21(g) of the regulations.
For purposes of the taxation of fringe benefits under section 61 of the Internal Revenue Code, section 1.61-21(g) of the Income Tax Regulations provides a rule for valuing noncommercial flights on employer-provided aircraft. Section 1.61-21(g)(5) provides an aircraft valuation formula to determine the value of such flights. The value of a flight is determined under the base aircraft valuation formula (also known as the Standard Industry Fare Level formula or SIFL) by multiplying the SIFL cents-per-mile rates applicable for the period during which the flight was taken by the appropriate aircraft multiple provided in section 1.61-21(g)(7) and then adding the applicable terminal charge. The SIFL cents-per-mile rates in the formula and the terminal charge are calculated by the Department of Transportation and are reviewed semi-annually.
The following chart sets forth the terminal charges and SIFL mileage rates:
| Period During Which the Flight Is Taken | Terminal Charge | SIFL Mileage Rates |
| 1/1/05 - 6/30/05 | $35.49 | Up to 500 miles = $.1942 per mile |
| 501-1500 miles = $.1480 per mile | ||
| Over 1500 miles = $.1423 per mile |
